You can connect to the internet using DSL, a cable modem or even LAN. In order for this article to be useful to you in troubleshooting your connection, it is expected that you will have a digital subscriber line, a cable modem or alternatively a local area network. If you lack any of them then that could be the main reason why you are not connecting to the internet.
Some computers are able to use an Ethernet port or an AirPort base station in order to get to any one of the services that have been mentioned above. Please note that Wi-Fi connections are also included in the triple list of options above.
Deciphering DNS-Related Messages
Sometimes you will get a series of messages that will inform you that the connection is not working. However if you are unable to interpret what they are saying then you are basically back to square one.
For example you may be able to connect to the internet but are then unable to load any or some webpages. The messages that you get will either tell you that the server could not be found or that a connection failure occurred. The system may make a few attempts before finally giving you the option to abandon the task. Excessive delays in responding or partial downloads are also not acceptable for optimum internet functionality. These problems could be related to the DNS configuration and whether the names given correspond to the right IP addresses.
Those who are using Mac OS may notice that there is some significant delay in loading web pages and then suddenly they load at normal speed. There could be a problem of freezing mid page particularly if the page contains some rich media. In this case you will need to upgrade the application that is reading the media. Flash has been giving users a lot of problems and many have reported that they can usually get round it by upgrading to the latest version.
The older dial up systems
Connectivity problems still affect the old PPP systems. These are the dial up connections that we associated with the first steps in internet access. Sometimes they are even more basic with the use of a Plain Old Telephone Service or POTS. In this case you will need to test the cable and then also the ability to ring the line. It could be that the line is dead and that is why you are not getting any responses.
Alternatively you can turn on the network discovery system in order to tell you the connection state of all your entry points. Ensure that you configure all your files and printers to be shared so that you can send data as and when required.
Your software manufacturer may also have some firmware that can be used to diagnose the connection and offer solutions without you having to unpack the entire connection. Some networks have passwords and if you do not have the right one then you will be locked out. Ensure that you have a good password management system.
